What is negative ion?

Ions are invisible particles, either molecules or atoms, which bear an electric charge. Atoms, for instance, consist of an atomic nucleus that contains neutral neutrons and positively charged protons, as well as orbiting electrons that are negatively charged. When an atom is in a neutral condition, the number of protons (+) and electrons (-) is equal. When the number of protons and electrons is not the same, the particle becomes an ion that is either positively or negatively charged.
